ABSTRACT

Objective : The aim of this study was to verify the reliability and validity of the Assessment of Home-based Activities (AHA), which can assess the elderly’s performance of daily activities at home in the three areas of independence, difficulty, and safety. Methods : A total of 360 elderly people aged 55 or older without physical disorders participated in this study. To verify the reliability and validity of AHA, the internal consistency, test-retest reliability, convergent validity, and discriminant validity were analyzed. Of them, we calculated the convergent validity, and the correlations between each activity of the AHA and Korean-Activities of Daily Living (K-ADL)and between each activity of the AHA and Korean-Instrumental Activities of Daily Living (K-IADL) were examined. In addition, to test the discriminant validity, the performance of daily activities between the group of general elderly and the group of elderly after a stroke was compared. Results : The internal consistency was within the range of .91 to .98 and the test-retest reliability showed a range of .78 to .86. The convergent validity showed that the correlations of all sets of two activities with similar names or features were statistically significant (p<.01). The discriminant validity showed that the general elderly people performed daily activities at a higher level than the elderly after suffering a stroke in all areas (p<.01). Conclusion : The AHA is a suitable instrument that can assess the performance of daily activities at home of elderly people, and is expected to be useful in implementing interventions of training for activities of daily living and home modifications in the field of rehabilitation.
